A floor hinge comprises a square body(10), a cylinder, a anti-separation lid(16), a rotating unit(20), a second spring(22), a roller guide(24), an oil guide(26), and a rotation guide. The square body has a space. The cylinder includes a first spring(12) therein and is diagonally installed to one corner of the body. The anti-separation lid is configured to prevent the first spring from being out of the cylinder. The rotating unit is diagonally attached to the other corner of the body, and rotated by a hinge shaft. The first spring of the cylinder contact to one end of the rotating unit. The second spring is installed in the rotating unit. The roller guide is installed in the second spring to open and close the door. The oil guide links with the second spring and causes the roller guide to move slowly when the door is closed. The rotation guide is formed like an arc in the body to help with rotation of the rotating unit. The oil guide includes a speed control valve(34) for controlling closing speed of the door.

상기와 같이 구성된 본 발명에 따른 플로어 힌지의 동작을 도 4를 참조하여 설명하면 다음과 같다.The operation of the floor hinge according to the present invention configured as described above will be described with reference to FIG.

먼저, 도어가 개폐되는 바닥의 일측에 본 발명의 플로어 힌지를 설치한 후, 도어의 일측 저면에 플로어 힌지의 힌지축(18)을 연결시킨다.First, the floor hinge of the present invention is installed on one side of the floor on which the door is opened and closed, and then the hinge shaft 18 of the floor hinge is connected to the bottom surface of one side of the door.

그리고, 도어가 닫혀진 상태에서 도어를 열면, 본 발명의 플로어 힌지의 힌지축(18)이 회전된다.Then, when the door is opened while the door is closed, the hinge shaft 18 of the floor hinge of the present invention is rotated.

상기 힌지축(18)의 회전에 따라, 본체(10)의 타측 모서리에 대각선 방향으로 일정길이 형성된 추형상의 회동부(20)에 조립된 로울러(36)가 호형상의 회동가이드(28)의 내주면을 따라 구르며 회동된다.As the hinge shaft 18 rotates, the roller 36 assembled to the pivotal rotating portion 20 having a predetermined length in the diagonal direction at the other corner of the main body 10 is formed of the arc-shaped rotating guide 28. It is rolled along the inner circumference.

이때, 상기 본체(10)의 일측 모서리에 대각선 방향으로 일정길이 고정 설치된 실린더(14)가 제1스프링(12)의 복원력에 의해 상기 회동부(20)에 접촉된다. 또 한, 상기 도어의 닫힐 시, 회동부(20)에 접촉된 실린더(14)가 힌지축의 회동부(20)에 의해 밀려나며 실린더(14) 뒤쪽의 오일을 밀어낼 때 오일의 유동량을 조절하기 위한 속도조절밸브(34)에 의하여 힌지축(18)의 회전속도가 조절된다. 그리고, 사용자가 무리한 힘을 가할 때, 상기 오일가이드(26)는 일시에 과도한 유동량이 발생될 경우에는 오일가이드(26) 이외에 과압 방지 오일가이드(27)를 더 설치하여 조절하는 것이 바람직하다. 구체적으로 본 발명에 따른 바람직한 과압 방지 오일가이드는 도 5에 도시한 바와 같이 과도한 오일의 유동량이 발생하면 과압 방지 밸브(27) 내에 설치된 볼 밸브(42)가 스프링(44)을 제1 오일 분산관(46)까지 수축시켜서, 실린더 내부에 연결된 제1 오일 분산관(46)과 실린더 뒤로 연결된 제2 오일 분산관(48)으로 과도한 오일의 유동량을 분산시켜서 힌지의 파손을 방지한다. At this time, the cylinder 14 fixedly installed at a predetermined length in a diagonal direction at one corner of the main body 10 is in contact with the pivot 20 by the restoring force of the first spring 12. In addition, when the door is closed, the cylinder 14 in contact with the rotating part 20 is pushed by the rotating part 20 of the hinge shaft and adjusts the flow rate of the oil when pushing the oil behind the cylinder 14. The rotation speed of the hinge shaft 18 is controlled by the speed control valve 34. In addition, when the user applies an excessive force, the oil guide 26 may be installed by adjusting an overpressure preventing oil guide 27 in addition to the oil guide 26 when excessive flow amount is generated at one time. Specifically, in the preferred overpressure preventing oil guide according to the present invention, as shown in FIG. By contracting up to (46), the excess oil flow is dispersed into the first oil dispersion pipe 46 connected inside the cylinder and the second oil dispersion pipe 48 connected behind the cylinder to prevent breakage of the hinge.

한편, 상기 실린더(14)의 오일이 유동하는 한 부분에는 각 부분의 마찰에 의해 발생되는 쇳가루를 모아주는 영구자석(13)이 설치된다.On the other hand, a portion of the oil flow of the cylinder 14 is provided with a permanent magnet 13 to collect the crushed powder generated by the friction of each part.

이상에서 상술한 바와 같이 본 발명은 도어가 닫힐 때 도어의 닫히는 속도가 일정하게 천천히 이루어짐으로 인해, 문틀과 도어 사이에 물건이나 신체의 일부가 끼는 문제점을 해결 할 수 있는 효과가 있다. 또한, 도어가 닫힐 때 닫히는 방향으로 무리한 힘이 가해질 경우 과도한 압력에 의하여 유압이 고장나는 경우를 대비하여 과도한 압력 발생시 힌지의 파손을 방지하는 효과가 있다.As described above, according to the present invention, since the closing speed of the door is made constant and slow when the door is closed, there is an effect of solving a problem that an object or a part of the body is caught between the door frame and the door. In addition, when an excessive force is applied in the closing direction when the door is closed, there is an effect of preventing the breakage of the hinge in the event of excessive pressure in case of hydraulic pressure failure.

이로 인해, 문틀과 도어 사이에 물건이나 신체의 일부가 끼는 문제점을 해결할 수 있는 효과가 있다.As a result, there is an effect that can solve the problem that the object or part of the body is sandwiched between the door frame and the door.

또한, 본 발명은 도어가 닫힐 때 실린더가 추형상의 회동부에 의해 움직이며 오일을 밀어내는데 이때, 오일이 통과하는 경로의 단면적을 가감하여 힌지축의 회전속도를 조절할 수 있도록 한 효과가 있다.In addition, the present invention has the effect of adjusting the rotational speed of the hinge shaft by adding or subtracting the cross-sectional area of the passage through which the cylinder is moved by the pivotal rotating portion when the door is closed, the oil passes.
